Below I have written some things you should check/ do to help you connect to your WIFI:
1. Ensure that Wi-Fi is turned on in your laptop settings. Sometimes, there may be a physical switch or function key that needs to be turned on.
2. Restart your laptop and your Wi-Fi router. This can sometimes resolve connectivity issues.
3. Check that Airplane Mode is turned off.
4. Run the built-in network troubleshooter. On Windows, go to Settings > Network & Internet > Status > Network troubleshooter.
5. Check your Wi-Fi is set to automatically detect networks. Go to Network & Internet settings, click on Wi-Fi, and ensure "Show available networks" is enabled.
6. Although you mentioned being near the router, verify there are no obstructions or electronic devices causing interference.
7. Forget the network and try reconnecting. Right-click on the Wi-Fi icon in the taskbar, select "Open Network & Internet settings," then "Wi-Fi" and "Manage known networks." Select your network and choose "Forget." Then try to reconnect.
8. Check the router is broadcasting its SSID (network name). Access your router settings via a web browser and check the configuration to make sure the SSID broadcast is not hidden.
9. If possible, check if other devices can see the network. If they can, your laptop’s Wi-Fi card might be the issue. Alternatively, try changing the channel on which your router broadcasts.
10. If all else fails, reset the network settings on your laptop. On Windows, go to Settings > Network & Internet > Status > Network reset.
If these steps do not resolve the issue, it might be a hardware-related problem with your laptop's Wi-Fi adapter.
